Thanks guys for your input on that one.
Hope that helps, Matthew. If you get the chance to weigh your recently purchased powerball you will be able to compare it to the original. By the way, guys, is the powerball the same size as a steel ball?
Certainly the lighter powerball (65g) is available overseas as per links provided earlier; Maxwiz it sounds like your scales need adjusting as they are most likely 3-4g out.
